Such code is verbose, hard to read, and, judging by the bugs and missing
specializations I've found, hard to write correctly. It is also not compatible

CTFE does support things like:

    double d;
    int i = *(cast(int*)&d);

as a special case, specifically to support bit manipulation of floating point 
types.
